Abstract

Abstract : Biomass-derived metal–organic hybrids show high performance in the transformation of CO2 to cyclic carbonates under ambient conditions. Abstract : The fabrication of catalysts that can activate CO2 under ambient conditions is very interesting but challenging. Metal–organic hybrids (MOHs) have promising applications in catalysis, and their fabrication from renewable resources is very attractive. Herein, we report a simple protocol to fabricate metal–organic hybrids (MOHs) from chitosan, phytic acid and ZnCl2, obtaining mesoporous MOH-Zn possessing –OH, –NH2, and –PO4 groups. The resulting MOH-Zn shows excellent activity for CO2 activation and enables the cyclization of epoxides with CO2 to proceed under ambient conditions, affording a high turnover frequency of 7.8 h −1 . The high performance of MOH-Zn originates from the synergistic effects among multi-functional sites in the catalysts.
